INDUSTRY CANADA RADIO FREQUENCY INTERFERENCE STATEMENTS
This equipment generates, uses, and can radiate radio-frequency energy,
and if not installed and used properly, that is, in strict accordance with the
manufacturer’s instructions, may cause interference to radio communication.
It has been tested and found to comply with the limits for a Class A computing
device in accordance with the specifications in Subpart B of Part 15 of FCC rules,
which are designed to provide reasonable protection against such interference
when the equipment is operated in a commercial environment. Operation of
this equipment in a residential area is likely to cause interference, in which case
the user at his own expense will be required to take whatever measures may be
necessary to correct the interference.
Changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.
This digital apparatus does not exceed the Class A limits for radio noise
emission from digital apparatus set out in the Radio Interference Regulation
of Industry Canada.

Chapter฀1:฀Specifications1.฀Specifications1.1฀Interfaces1.1.1฀DVI-D฀Single฀LinkThe video interface supports the DVI-D protocol. All signals that comply with
DVI-D single-link standard can be transmitted. This includes, for example, monitor
resolutions฀such฀as฀1920฀x฀1200฀@฀60฀Hz,฀Full฀HD฀(1080p),฀or฀2K฀HD฀(up฀to฀2048฀x 1152). Data rate is limited to 165 MPixel/s.
1.1.2฀USB฀HIDDevices with USB HID interface support a maximum of two devices with
USB HID protocol. Each USB HID port provides a maximum current of 100 mA.
Keyboard
Compatible with most USB keyboards. Certain keyboards with additional
functions may require custom firmware to operate. Keyboards with an integral
USB Hub (Mac®keyboards, for example) are also supported.
Mouse
Compatible with most 2-button, 3-button, and scroll mice.
Other฀USB฀HID฀devicesThe proprietary USB emulation also supports certain other USB HID devices, such
as specific touchscreens, graphics tablets, bar-code scanners, or special keyboards.
Support cannot be guaranteed, however, for every USB HID device.
NOTE: Only two USB HID devices are supported concurrently, such as keyboard
and mouse or keyboard and touchscreen. A hub is allowed, but it does not
increase the number of HID devices allowed.
To support other USB “non-HID” devices, such as scanners, Web cams or memory
devices, choose our devices with transparent USB support.
1.1.3฀RJ-45฀(Network)CATx device communication requires a 1000BASE-T connection. Pin the cable
according to EIA/TIA-568-B (1000BASE-T) standard with RJ-45 connectors at both
ends. All four wire pairs are used in both directions. The cabling is suitable for
full-duplex operation. For the cable connection to a source (computer, CPU), use a
cross-pinned network cable.

Page 12 724-746-5500 | blackbox.com
Chapter฀1:฀Specifications1.1.4฀RS-232฀(Serial)The communication takes place with a transmission speed of up to 115.2 kbps,
regardless of the file format, eight data bits and a stop bit, but without a parity
bit. Limited hardware handshake (DSR) is possible.
1.1.5฀RJ-45฀(Interconnect)CATx device communication requires a 1000BASE-T connection.
Connector wiring must comply with EIA/TIA-568-B (1000BASE-T), with RJ-45
connectors at both ends. All four wire pairs are used.
1.1.6฀Fiber฀SFP฀Type฀LC฀(Interconnect)Fiber device communication is performed via Gigabit SFPs connected to suitable
fibers fitted with LC connectors (see Section 1.2.2).
NOTE: The correct function of the device can only be guaranteed with SFPs
provided by Black Box.
CAUTION: SFP modules can be damaged by electrostatic discharge (ESD). Follow
ESD handling precautions.
1.1.7฀SDI฀(Interconnect)SDI device communication requires a mini coax connection with mini BNC
connectors or 3G SFPs with transmission speeds of 0.360 Gbps (SD-SDI, SMPTE
259M), 1.485 Gbps (HD-SDI, SMPTE 292M), and 2.70 Gbps (3G SDI).
1.2฀Interconnect฀Cable1.2.1฀CATxNOTE: A point-to-point connection is required. Operation with several patch fields
is possible. Routing over an active network component, such as an Ethernet
hub, router, or ServSwitch DKM FX, is not allowed.
•฀Avoid฀routing฀CATx฀cables฀along฀power฀cables.
•฀฀If฀the฀site฀has฀three-phase฀AC฀power,฀make฀sure฀that฀the฀CPU฀Unit฀and฀CON Unit are on the same phase.
NOTE: To maintain regulatory EMC compliance, use correctly installed shielded
CATx cable throughout the interconnection link.
NOTE: To maintain regulatory EMC compliance, all CATx cables need to carry
ferrites on both cable ends close to the device.
Type of Interconnect Cable
The ServSwitch DKM FX requires interconnect cabling specified for Gigabit
Ethernet (1000BASE-T). Use solid-core (24 AWG), shielded, CAT5e (or better)
cable.

This S/UTP (CAT5e) cable confoms to EIA/TIA-568-B.
Uses four pairs of 26/8 AWG wires. Connects according
to EIA/TIA-568-B (1000BASE-T).
NOTE: You can use use type 26/8 AWG flexible cables (patch cables), but the
maximum possible extension distance is cut in half.

2. Overview
2.1฀Description2.1.1฀ApplicationThe ServSwitch DKM FX is used to establish connections from consoles (monitor,
keyboard, mouse, and other peripheral devices) to various sources (computer,
CPU). In a maximum configuration, up to 288 independent ports can be defined
and switched either as a console or a CPU.
The ServSwitch DKM FX Compact is used to establish connections from consoles
(monitor, keyboard, mouse, and other peripheral devices) to various sources
(computer, CPU). In a maximum configuration, up to 16 (using the ACXC16), 32
(using the ACXC32), or 48 (using the ACXC48) independent ports can be defined
and switched either as a console or a CPU.
The ServSwitch DKM FX is mainly specified for the use with extenders that are
able to transmit video, KVM, and USB 2.0 signals. You can also use it as a video
matrix.
For the connection between the ServSwitch DKM FX and the peripheral devices,
such as KVM extenders or video sources, you can use CATx, fiber, or coaxial
cables.
The ServSwitch DKM FX serves as a repeater. You can place it up to 6.2 miles
(10 km) from the consoles and 6.2 miles (10 km) from the sources.
2.1.2฀Access฀OptionsYou have the following options to access the ServSwitch DKM FX for
configuration and operation:

2.2 System Overview
A ServSwitch DKM FX system consists of a ServSwitch DKM FX or DKM FX
Compact and, for KVM applications, one or more CPU units/CON units. The
ServSwitch connects to the CPU units/CON units by interconnect cables or is con-
nected directly to the video devices when used as a video matrix.
The CPU units connect directly to the sources (computer, CPU), using the included
cables.
Monitor(s), keyboard, and mouse connect to the CON units.
The ServSwitch DKM FX and the CPU units/CON units communicate over CATx,
fiber, or coaxial interconnect cables. The ServSwitch DKM FX Compact and the
CPU units/CON units communicate over CATx cable.
Figure 2-1 shows the system overview. Table 2-2 describes its components.
